摘要： PURPOSE:To permit the removal of the adhered ash of fuel efficiently with a high workability by a method wherein a viscous gelling substance having a high water content is adhered to the surface of the adhered ash and the outside thereof is covered by a film type substance having a low water transmittance to soften the adhered ash with moisture in the gelling substance and remove it physically from the adhering surface of the ash. CONSTITUTION:A viscous gelling substance having a high water content is applied on the surface of adhered ash 2 accumulated on a heat transfer tube 1 with the thickness of 1-2mm. Next, the outer surface of the coated gelling substance 3 is covered with a film 4 formed of a substance having a low water transmittance. In this case, the film 4 is constituted of a substance, precluding the dispersion of moisture in the gelling substance 3 and having a function to impregnate the moisture into only the adhered ash 2. When the film 4 is applied, the gelling substance and the film are left for several hours. During this period, the moisture in the gelling substance is impregnated into the adhered ash to wet and inflate it. Thereafter, the film 4 is removed and the applied gelling substance 3 as well as the objective adhered ash 2 may be separated from the heat transfer tube 1 easily by a scraper and the like.

摘要： PURPOSE:To adjust excess heat absorbing quantity at new tube part by flame spraying iron or ferrous alloy on outer circumferential face of a boiler steel tube for heat exchanger so as to become close near the tube wall and coarser in accordance with further from this. CONSTITUTION:At the time of renewing a part of the boiler steel tube for heat exchanger, the iron or the ferrous alloy is flame sprayed on the outer circumferential face of the new tube for renewing. In this flame spraying the flame spraying layer 2 is formed so that the flame spraying particles 3 become close near the boiler tube wall 1 and coarser in accordance with further from this. In this coarse part, oxide 4 of the iron component in the flame spraying particle 3 is rapidly generated and combustion ash 5 is deposited for a short time at the time of starting the boiler operation. By this reason, heat conductivity of the tube is lowered to the same degree as the other old tube and locally excess heat absorbing quantity is simply prevented.

摘要： PURPOSE:To simplify the maintenance with a quick and accurate measurement of pH value of feed seawater by determining the absorbancy thereof when light from a light source transmits a measuring cell containing the feed seawater colored in accordance with its pH. CONSTITUTION:With the opening or closing of a solenoid valve 8, a fixed amount of a feed seawater to a decarboxylation column is stored in a measuring cell 9 through a sampling tube 7. When the quantity of the seawater reaches a fixed level in the cell 9, with the opening or closing of a solenoid valve 18, a specified amount of color developing agent is dripped from a vessel 17 for the color developing agent. At the same time, an ultrasonic vibrator 13 works to mix the feed seawater and the color developing agent uniformly in the cell 9 so that the feed seawater is colored according to its pH. Subsequently, an absorptiometer 20 is actuated. Light received by a photo detector 16 is absorbed by the colored sea water in the cell 9 according to the hue thereof thereby enabling the measurement of the pH value of the feed seawater depending on the absorbancy thus obtained.

摘要： PROBLEM TO BE SOLVED: To improve the wear resistance without deteriorating corrosion resistance by ion-nitriding an austenitic stainless steel, heating and oxidizing the steel in a high-temp. and high-pressure deaerated water. SOLUTION: The free Fe in an ion-nitrided nitride layer is heated in a high- temp. and high-pressure deaerated water or in a high-temp. and high-pressure deaerated steam. A reaction 3Fe+4H2 O → Fe3 O4 +4H2 proceeds, and the Fe is converted to stable black Fe3 O4 (ferric-ferrous oxide). Although the final oxide is Fe2 O3 in the air, Fe3 O4 is the final oxide in the high-temp. and high- presssure water or in the high-temp. and high-pressure deaerated steam. Fe3 O4 is not changed into an yellowish-brown rust such as Fe2 O3 FeOOH. The oxidation does not proceed, and a material having wear resistance while maintaining corrosion resistance is obtained.

摘要： PURPOSE: To remove phosphates in waste liquid effectively and to contrive to save resources and to reutilize wastes by bringing solid wastes contg. a large amt. of Ca and F compds. contained in the waste water of stack gas desulphurization process into contact with the water to be treated.
CONSTITUTION: The water to be treated 1 is mixed and brought into contact with powdery sludge 3 and recycled seed crystals 7 in a crystallization reaction vessel 2. In this stage, the phosphates contained in the water to be treated deposit on the surface of the powdery sludge 3 and the recycled seed crystals 7 in the form of crystals of calcium phosphate. At the start of the operation, the powdery sludge is charged in a proportion to obtain 5W10g/l liq. mixture, but the amt. of the charge is set in the stationary state of the operation to obtain a weight ratio of Ca contained in said powdery sludge to the phosphate contained in the water to be treated to be 1:(3W5). The liquid mixture in the crystallization reaction vessel 2 is transferred to a precipitation vessel 5 where it is separated into water to be treated 6 and seed crystal 7 to be recycled.

摘要： PURPOSE:To make a deodorizing equipment compact and automatic and to prolong the life of active carbon, by providing a cover to a refuse pit chamber and performing dust-removal and chemical washing before active carbon adsorption, in a process that an atomospheric gas in the pit chamber of the titled plant is sucked into an active carbon adsorbing tower. CONSTITUTION:When deodorizing of atmospheric gas in a refuse pit chamber 1 is required, a little volume of the gas is sucked from a hole 5 by a fan 8 after covering the whole chamber 1 with a cover 2. The gas removed dust in it by a filter 6 is washed with an aqueous sodium hypochlorite solution and discharged to the air after the odorous components are adsorbed by an active carbon adsorbing tower 9. The cover 2 is equipped with an automatic open-and-close mechanism; the opening and closing of the cover 2 and the deodorizing equipment are automated to work by an electric signal when refuse are charged into the chamber 1 from a dump truck. Thus a diffusion of the gas is prevented in a case that the function of an incinerator stops and the chamber 1 is not used for combustion air. Further, the equipment is made compact because the sucked gas quantity is decreased. Further, the function of the equipment is always displayed by said automation.

摘要： PURPOSE:To enable invariably stable high-efficient processing by processing thick waste water containing organic matter under semiaerobic and semilight conditions. CONSTITUTION:Thick waste water containing organic matter such as raw sewage is flowed from line 1 into incubation tanks 2a and 2b. Fresh air, oxygen or gas containing oxygen coming from line 7 is mixed by mixer 10 with gas exhausted from tanks 2a and 2b via exhaust lines 20a and 20b. This mixed gas is dispersed into the waste water in tanks 2a and 2b by sparger 6a and 6b by way of feed lines 19a and 19b to stirr the waste water. In this case, O2 concentration in the mixed gas is controlled. Tanks 2a and 2b are irradiated with light to incubate purple nonsulfur bacteria with organic matter in the waste water, thereby decomposing and removing organic matter in the waste water. Here, seed germs are supplied via line 27.
